Contact Blocks

Contact Blocks — New & Used

Contact blocks are electromechanical switching components used in control systems, machinery, and industrial panels. They serve to open or close electrical circuits — integral for start/stop buttons, safety circuits, control relays, and operator interface systems.

Find Your Contact Block Fast (Search-First)

Search by part number or contact-block spec (e.g., single-pole contact block, 3-pole maintained contact block, MCC contact block used).
No part number? Try keywords like “industrial contact block”, “safety switch contact module”, or “push button contact block surplus”.
Filter by pole count, contact type (momentary / maintained), voltage/current rating, or manufacturer to narrow search.
